[Savage40] Long-Standing Bug

[Tim Roberts]

For those of you who are still able to apply active resources to the 
Savage driver, there is one outstanding bug that has caused much concern 
that shouldn't be terribly difficult to chase down.

The problem happens when you try to display a gradient background with a 
window manager.  When you do so, you see obvious striping in the colors 
-- striping that you should not see at depth 24.  It looks as bad or 
worse than depth 16.

This bug seems to have been introduced in the 1.21t timeframe, at the 
same time I added support for the xgamma extension.  When I did that, I 
also increased the "number of DAC bits per component" from 6 to 8.  I 
_suspect_ the striping bug is related to that change.  Someone, 
somewhere, is still confused about the DAC depth, and is masking off 2 
bits that it shouldn't.

Volunteers?
